SC16P RTC_CR for MK22FN128VDC10

thoomanwang — Sat, 15 Oct 2016 09:50:30 GMT

RTC_CR has a field SC16P for MK22FN128VDC10

Whether I use RTC_CR to configure external crystal vibration load capacitance, no longer need to welding load resistance?

Hi Thooman,

If you use the internal capacitor by configuring the RTC_CR, and your board's crystal can oscillating after enable the OSC, then you don't need to welding external load capacitor.

But I suggest you add the external capacitor pcb package for the hardware crystal circuit testing.

Wish it helps you!

If you still have question, please let me know!

Have a great day,
Kerry
